Phantom 2. GPS mode, other switch in home lock mode. I flip the right switch 5 times per manual, do the first rotation. No light change. Flip the 6th time and do the other rotation. No light change. Turn the bird battery off, then power up again. All lights flash a few times then the yellow lights come on steady again. Why? If I have the right switch in atti mode, all lights come on as normal and ready to fly.
